Anyone have these numbers from a real dyno run, STOCK, perhaps with a pic or link to the dyno graph? If not, real numbers would be fine. Just curious as to what these old beasts put down in total STOCK trim at the wheels. Dyno numbers from all three gen'* of SSEi'* would be cool too.

I think factory was about 245hp....Not positive I can look in my book when I get home, but I think 245 is about right.

92-93

205hp
260tq


94-95

225hp
275tq


96-99


240hp
280tq


These are the numbers that i have been given through factory brochures from dearlers, books and other sources. I dont know what the dyno would say.

Stock GM factory ratings are 205hp for the 92/93, 225 for the 94/95, and 240 for the Series 2. Horsepower and torque factory ratings are in Techinfo, Specifications.

With that said, there'* alot of evidence to the contrary. Most cars come with more horsepower than the rating (as evidenced by numerous stock dyno pulls on CGP). To the best of my knowledge, no Series 1 SSEi has ever been on a dyno, much less in stock form.

There were quite a few changes between 92 and 93, yet the rating didn't change? I attribute that to someone'* laziness at GM.

When looking at the techinfo I couldn't find torque ratings and @ what RPM. I found this much for the '92:
The '92 SSE makes 170hp at 4800rpm and 220lb/ft of torque at 3200rpm. The '92 SSEI makes 205hp @ 4200rpm and 260lb/ft @ 2600rpm.

Well thanks so far guys. It looks like I'll be taking the 'ole SSEI over to the local dyno joint next week and giving it a whirl. I'd like a baseline so I can see where I'd be going after modding.

If you weigh your car at the local dragstrip, and then make a couple runs, you can back-solve for your hp. It'* actually pretty accurate.

Remember, your dyno numbers will be whp not bhp (crank). If your car is rated at 205 crank then you can expect to see about 165-170 at the wheel.

I cant wait to see these numbers. I had a guy tell me at the dealership that the 95 ssei'* had 170hp and that if you had the car for a while the hp changes because its and older car.

Basically yeah it does...Very new engines are tight and generally have more friction = little less hp. Old engines have larger clearances and carbon buildup = little less hp. How bad will dictate how much but not a lot I don't think.
